Surface roughness sensor for plastic surfaces 

for use with RS 232 series D522

Description:

A plastic surface can be analyzed for roughness. The sensor measures roughness from 0.05 to 20 microns.  One light flash is used and the reflected and scattered light is used to calculate roughness. The results of these measurements and calculations for roughness are sent to a PC.  The letters shown on the screen are the following for the measured values:

SCA = scattered light    REF= reflected light    ROU = roughness in micron    TEM = ambient temperature

Personalize:

Like any analytical instrument there are many other things you can do with it.  For instance instead of measuring roughness from a surface it is possible to use this sensor to calibrate to reflectivity. The output from your measurement shows in the Palm and instead of using the calculated data’s from the sensor you can create your own calibration by using the formulas above or other manipulations.

Calibration:

Hohner calibrates the ROU = roughness  with calibration samples in the microprocessor from the sensor.  To recalibrate simply use the calibration samples or your own calibration samples and go with the formula above in your Palm by ignoring the existing coming from the sensor. You always can use the values from the sensor as default. You can calculate the new values  or put the formula in your Palm software.
